heres a great tip.
dont breed
i mean if you thought it out i assume you already have homes for the babies?
i am not trying to sound rude its just sooo many babies die, why breed more?
if you are going to breed i dont really have much help for you. i myself in my younger days used to breed for petstore feeders (not something i am proud of now) and i didnt never pay attention to genetics, etc. i know when she was about to give birth i woud take the male out. id leave the rest of the female in there, they usually helped her out. and after the babies are 4 or 5 weeks old and eating solid foods i would sex and seperate them.
when mom is prego feed her high protein food. i would also say dont disturbe her nest. one reason why i quit breeding (not to mention now i am ashamed i used to do that horrific crap!) was because the mom would always eat her babies. i am guessing its because i would distrube the nest three or four days after they were born.
i am sure someone would be of more help. but from what i know on this forum, they will tell you what i did...
